Felsic: Definition & Composition Definition of Felsic Rocks. Felsic rocks are igneous rocks that are rich in feldspar and silicon. The word 'felsic' was made up from parts of those words. Because they are made of lighter elements, they tend to be more buoyant than mafic rocks, which are rocks high in magnesium and iron, like basalt. Granite is the most common felsic rock.

What is the definition of mafic? Rockhound. Mafic is a term used to describe an igneous rock that is usually dark in color, with a chemistry that may be high in magnesium and iron, like basalt. Mafic is also a term used to describe a type of magma that is high in calcium, magnesium and iron, and relatively low in silica, compared to felsic magma.afic is also a term used to describe a type of magma that is high in calcium, magnesium and iron, and relatively low in silica, compared to felsic magma.

Volcanism I: Sources and Composition of Magma As ultramafic magmas encounter the felsic rocks of the continental crust, they cause the most felsic minerals in those felsic rocks (the ones with the lowest melting point) to melt. Thus, felsic material is added to the magma as mafic material is lost to fractional crystalization.

Ask GeoMan... The most common felsic rock is granite, which represents the purified end product of the earth's internal differentiation process. It is important to note that there are many intermediate steps in the purification process, and many intermediate magmas which are produced during the conversion from mafic to felsic.

What's Andesitic, Mafic, and Felsic? Basically, magma tends to evolve from mafic composition of the mantle to the felsic composition of the crust. Tend to find andesites in areas where the source rock is a mix of mantle-derived and crustal-derived materials, such as would be found near subduction zones.

- Felsic rocks are dominated by minerals that are light in color, such as quartz, feldspar, and mica. The extrusive rock rhyolite and its intrusive counterpart gran-ite are examples of felsic rocks. Mafic rocks are dominated by minerals that are dark in color, such as amphibole, pyroxene, and olivine. Exam-ples include the extrusive rock basalt and the intrusive rocks gabbro and diabase. Many felsic rocks form from magma that originated in continental crust.

Mafic The mafic rocks also typically have a higher density than felsic rocks. The term roughly corresponds to the older basic rock class. Mafic lava, before cooling, has a low viscosity, in comparison with felsic lava, due to the lower silica content in mafic magma. Water and other volatiles can more easily and gradually escape from mafic lava.
